I made my own masters from clay (baked in the oven) and the molds were made off of that master out of oomoo.
I pour my plastics with no color added, only glitters, but my clear always comes out frosted.
I sanded the master smooth with a very fine sandpaper, but i have not sealed it with anything.
Is it my oomoo mold or the clay master?
Thanks, I wish i found this site sooner!
